OFB-8

what happened, like: "you lost, you made me rage quit," is considered unfair play because, even if you didn't know the rules, you deceived your opponent, forcing them to admit defeat and say the password (if it makes it easier for you, it's just a scam to get the password and reveal the map), so you are to blame. Is there anything else I need to explain to you?

What is this nonsense about unfair play? Unfair play is when you deliberately do something against a person and not according to the rules. The point is that BOTH made a mistake. In this situation, in the organizer's place, I would either give extra time for another game (after all, the next round is the last) or take the saves from this game for judging (only objectively).
